I must have spoken too soon.
After saying just the other day that we'd travelled 30,000km on our custom made bikes without a problem, yesterday we discovered a crack in Andrew's frame. Just a small one, where the back rack attaches to the frame. We found a motorbike shop run by a French guy here in Phnom Penh and he seemed pretty competent so we're getting it fixed up now.
My question is, assuming he does a reasonable job of welding the crack, is the frame going to be as strong as before, stronger or is this just a sign of imminent demise that we'll only put off by fixing?
Also, what is the most likely cause of the crack? The French guy said it was overloading. Plausible. We haven't given the bike any knocks that we know about.
What kind of life would you expect out of a well built touring bike - 50,000km? Nothing lasts forever I guess, though I wish it would...
